Rice Research Institute b. Genetically modified organism produced by Philippine researchers c. Issues on Philippine biosafety policies

Genetically modified organisms (GMOs) have been a subject of controversy and debate worldwide, including in the Philippines. While GMOs offer potential benefits in terms of increased crop yields and pest resistance, their potential impacts on human health and the environment should not be overlooked.

The use of GMOs in the Philippines has been a contentious issue due to concerns about the safety of these organisms and their potential impacts on human health and the environment. The Philippine government has responded to these concerns by implementing biosafety policies aimed at regulating the use and release of GMOs. One of the key impacts of GMOs on Philippine biosafety policies is the need for a comprehensive and transparent regulatory framework.

Hence, GMOs have significant impacts on Philippine biosafety policies. The introduction of GMOs into the environment requires a comprehensive and transparent regulatory framework that takes into account potential risks and benefits.

Answer:

it can't be used to make a protein in that cell.

Explanation:

If a gene is not transcribed in a cell, it can't be used to make a protein in that cell. If a gene does get transcribed, it is likely going to be used to make a protein (expressed). In general, the more a gene is transcribed, the more protein that will be made.

The transcription is affected as when the gene has not been transcribed the protein will not make. When a gene is transcribed, protein synthesis can happen.

Gene expression begins with transcription. To create an RNA molecule, the DNA sequence of a gene must be copied. RNA polymerases, which join nucleotides to create an RNA strand, carry out transcription (using a DNA strand as a template).

A gene cannot be used to produce a protein in a cell if it is not transcribed there. If a gene gets transcribed, it will probably be used to produce a protein (expressed). In general, more protein will be produced the more a gene is transcribed.

Therefore, the transcription is impacted since the protein cannot be produced if the gene is not transcribed. Protein synthesis can take place when a gene is transcribed.

Environmental Factors Interact with Genes

Environmental factors often influence traits independently of genes. But not always. Sometimes the environment changes a gene—either its DNA sequence or its activity level. Either of these effects can change the proteins that are made from a gene, which in turn affects traits.

P I and PII are proteic compounds present in the thylakoid membrane that contain about 300 chlorophyll molecules each.

First of all light with a wavelength of 690nm is absorbed by P II. The light excites an  electron that leads to the photolysis of water(H2O--->2H+ +2e- + 1/2O2). The two electrons released go into the electron transport chain. The second compound in electron transport chain is plastoquinone that is reduced when it accepts electrons then oxidised when it loses them to P I. The next two compounds are cytocromes  that make  hydrogen protons  go inside the thylakoid when they recieve the electrons.(I will mention what happens to the  H+  in the second step). The next compound in the electron transport chain is a compound that contains Fe and S. The electrons finally reach the last step: Reduction of NADP+ to NADPH+H+.

In the second step is ATP synthesis. Hydrogen protons accumulate inside  the thylakoid membrane. An electrochemical gradient is formed. The protons can leave the thylakoid according to this gradient through an enzyme.

When the protons flow through , it turns ADP into ATP.

To sumarize: the role of P II is O2 production through photolysis and ATP synthesis(indirectly) The role of P I is NADPH+H+ synthesis.

The codon sequence on the mRNA strand determines the amino acid sequence of the polypeptide.

The coding section is the portion of the DNA that is also known as a gene. Genes are the functional units of DNA that provide the instructions for making proteins. They are composed of coding cells, also known as exons, that contain the information needed to build the polypeptide, and non-coding sections, also known as introns, that do not.

The codon sequence on the mRNA strand is translated by the ribosome during protein synthesis. Each codon, which is a sequence of three nucleotides, corresponds to a specific amino acid. The ribosome reads the codon sequence on the mRNA strand and adds the corresponding amino acids to the growing polypeptide chain. This process is called translation.

In DNA, genetic information is encoded in the sequence of nucleotides, which are the building blocks of DNA. Genes are specific segments of DNA that contain the instructions for making a specific protein. These instructions are encoded in the sequence of nucleotides within the coding sections of the DNA, also known as exons. The non-coding sections, also known as introns, do not contain instructions for making proteins, but they play important roles in the regulation of gene expression.

Cephalization is the concentration of sensory and nervous structures at the anterior (head) end of an organism. This concentration allows for more efficient and rapid processing of sensory information and quick responses to stimuli.

Having cephalization in one area of the body, specifically the head region, allows for the development of specialized sense organs, such as eyes and ears, which can better detect and process information. In addition, the concentration of neurons in the head region allows for more complex nervous processing, leading to greater cognitive abilities.

On the other hand, spreading out sensory and nervous structures throughout the body would lead to slower processing times and less specialization. This would not be advantageous in environments where quick responses to stimuli are necessary for survival, such as in predator-prey interactions or avoiding environmental hazards.

Therefore, having cephalization in one area of the body provides a significant advantage in terms of sensory processing, cognitive abilities, and survival.

Answer: Air, soil, water, light, salinity and temperature

Explanation: Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.

To answer this question we need to remember a bit of the earth's history. In the first stages, Precambrian, on earth, there was no oxygen, nonetheless with the rise of photosynthesis by cyanobacteria the concentration increased, nonetheless it was a gradual process, now also there was an increase in carbon dioxide levels at the end of the Mesozoic due to intense volcanic activity along with other factors. So taking this into consideration we can say that the correct answer is the third option, as a volcano is a sudden event and if large enough maybe it won't change all the atmosphere, but can generate a local change.

Carotid sinus syncope refers to a condition characterized by a sudden loss of consciousness or fainting (syncope) that occurs due to an abnormal response of the carotid sinus, a small structure located in the neck. The carotid sinus contains baroreceptors, which are sensory receptors that monitor blood pressure.

In the case of Ms. G, her episode of syncope while showering was likely triggered by the pulsatile shower head. The carotid sinus is sensitive to changes in pressure, and certain stimuli, such as pressure on the neck, can result in an overstimulation of the carotid sinus baroreceptors.

The pulsatile nature of the shower head may have caused an increased pressure or stimulation on Ms. G's carotid sinus during her shower. This excessive stimulation of the carotid sinus baroreceptors led to a reflex response that caused a sudden drop in heart rate and blood pressure, resulting in syncope.

Carotid sinus syncope is typically diagnosed based on the patient's history, clinical symptoms, and sometimes with additional tests such as carotid sinus massage or tilt table testing. Treatment options for carotid sinus syncope may include avoiding triggering factors, modifying lifestyle, and in some cases, medication or pacemaker implantation.
